IDS uEye camera control in .NET framework.

Hello, I am using the .NET framework with MATLAB to program the IDS ueye camera, but now I have problems with following issues:

I wanted to do the subsampling in both horizontal and vertical orientation, but from the uEye .NET manual, there is no options for subsampling in both orientation, here is the provided instruction from the manual:

cam.Size.Subsampling.Set(uEye.Defines.SubsamplingMode mode)

parameter mode options:

uEye.Defines.SubsamplingMode.Vertical2X

uEye.Defines.SubsamplingMode.Horizontal2X

uEye.Defines.SubsamplingMode.Vertical3X

uEye.Defines.SubsamplingMode.Horizontal3X

uEye.Defines.SubsamplingMode.Vertical4X

uEye.Defines.SubsamplingMode.Horizontal4X

uEye.Defines.SubsamplingMode.Vertical5X

uEye.Defines.SubsamplingMode.Horizontal5X

uEye.Defines.SubsamplingMode.Vertical6X

uEye.Defines.SubsamplingMode.Horizontal6X

IuEye.Defines.SubsamplingMode.Vertical8X

uEye.Defines.SubsamplingMode.Horizontal8X

uEye.Defines.SubsamplingMode.Vertical16X

uEye.Defines.SubsamplingMode.Horizontal16X

uEye.Defines.SubsamplingMode.Disable

There is no other options,but it says that the two parameters Vertical and Horizontal can be linked by logical OR, I tried to do that but failed and here is the error:

cam.Size.Subsampling.Set(uEye.Defines.SubsamplingMode.Vertical4X|uEye.Defines.SubsamplingMode.Horizontal4X);

Error : Undefined operator '|' for input arguments of type 'uEye.Defines.SubsamplingMode'.

cam.Size.Subsampling.Set(uEye.Defines.SubsamplingMode.Vertical4X | Horizontal4X);

Error : Undefined function or variable 'Horizontal4X'.

So do you know how to solve this problem? I am looking foward to you answer and I would be very appreciated about that

cam.Size.Subsampling.Set( bitor(uc480.Defines.SubsamplingMode.Vertical2X, uc480.Defines.SubsamplingMode.Horizontal2X) )

Thanks for your answer, is the 'uc480' the camera ID? Can I substitute the 'uc480' with 'uEye'?

[Yiyu Zhou]

Yes. The trick is bitor()
